Smoke billows from the Italian-flagged Norman Atlantic ferry that caught fire in the Adriatic Sea, Tuesday, December 30, 2014. A blaze broke out on the car deck of the Norman Atlantic Sunday, Dec. 28, while the ferry was traveling from the Greek port of Patras to Ancona in Italy causing the death of at least 11 people. Italian and Greek helicopter rescue crews evacuated 427 people among passengers and crew members but Italian officials think the death toll could be much higher because of serious discrepancies in the ship's manifest and confusion over how many people were aboard. “We cannot say how many people may be missing”, Italian Transport Minister Maurizio Lupi said at a news conference. The cause of the fire is under investigation. (Photo by Antonio Calanni/AP Photo)

The battleship USS Iowa fires its 16-inch guns during duty in the Persian Gulf on December 16, 1987. In 1943, the Iowa ferried President Franklin Roosevelt home from the Teheran Conference, where post-WW II leaders divided up the world. The ship fought battles from the South Pacific to Korea and escorted convoys through the Persian Gulf. Forty-seven sailors died atop its deck when an explosion ripped through a gun turret. Now, the new port for the retired USS Iowa just might be the home of California's annual asparagus festival, the gritty agriculture port town of Stockton on the San Joaquin River, about 80 miles inland from San Francisco.
